Used in biomedical research to detect and quantify levels of mouse calcium-binding protein (CR) in tissue extracts, serum, or cell culture samples. This ELISA kit enables researchers to study the expression and regulation of calretinin, a protein involved in calcium signaling, in neurological studies, cancer research (particularly mesothelioma and neuroendocrine tumors), and developmental biology. It supports high-throughput analysis with high sensitivity and specificity, making it valuable for investigating neuronal differentiation, neurodegenerative diseases, and biomarker discovery in mouse models.
